摘要
在某两座城镇污水处理厂提标改造工程中,将SBR等工艺改变为An/O和MBBR运行模式,强化了二级生物处理效果,使二级出水COD、BOD5、NH3-N和TN稳定达到一级A标准。同时,针对不同水质特点,选择不同的混凝沉淀和过滤形式进行深度处理,保证了SS和TP的稳定达标。
In the upgrading and reconstruction project of two municipal sewage treatment plants,the SBR process and other processes were changed to An/O and MBBR modes.The improved process enhanced the secondary biological treatment effect.The COD,BOD5,NH3-N and TN of secondary effluent achieved the standard of grade A.And according to the characteristics of the different water quality,different coagulation,sedimentation and filtration methods were selected for the advanced treatment,thus ensuring the SS and TP achieving the standard.
